Sample-Making

A sample is a prototype of your idea. Sample-makers usually make the product by hand (hand-cutting, hand-assembling, etc.) before you get your tooling finalized. You want your sample to be perfect if you plan to do mass production of your product.

The minimum order for a production run can vary from factory to factory (some have no minimum, some require a dozen, and some require up to 1,000 to be made at once)
